Where are latitude and longitude values stored and why?

• A. Stored with appropriate precision and caching
• B. Stored as integers representing minutes
• C. Not stored at all
• D. Stored in a separate text file

Answer: (A)

Latitude and longitude are real-valued coordinates expressed in degrees, so they must be stored with enough precision to preserve exact locations. Storing them as integers representing minutes loses sub-minute accuracy and makes conversions harder, and not storing them or putting them in a separate text file would either erase or isolate essential location data. The practical approach is to keep them as numeric values with appropriate precision (such as double-precision floats or fixed-point with several decimal places) so calculations and rendering remain accurate, and to use caching to speed up repeated access or rendering of commonly used coordinates. This combination explains why both precision and caching are the best practice.
